The 'Erm... What the Deuce' meme originated from the animated series Family Guy, specifically as a signature catchphrase of the character Stewie Griffin. Known for his sophisticated British accent and adult-like demeanor, Stewie uses this phrase to express shock, confusion, or disdain. In internet culture, the phrase has seen a massive resurgence as an ironic reaction image, often paired with a low-quality or wide-angle shot of Stewie. It is commonly used to respond to bizarre social media posts or confusing situations where a standard reaction simply isn't enough to convey the specific level of sophisticated bewilderment the moment requires.
